This grant will maintain and operate two coordinated 'Class I' optical instruments at the Polar Cap Observatory site for three consecutive seasons, as well as analyze data sets from these instruments to systematically address problems in mesospheric and thermospheric physics. The instrument, already in place, are a Fabry-Perot interferometer and a fully digital all-sky monochromatic imager system with thermoelectrically cooled bare CCD detector and programmable filter wheel. The two instruments, deployed in the 'Early PCO' building, completed their first full season of observations in May, 1996, and results have been presented. The Fabry-Perot interferometer is performing above expectations, and results will continue to be shared with the aeronomical community through CEDAR and Canadian sponsored efforts. In addition, these two instruments will provide training for Genene Fisher, a graduate student, investigating: (1) gravity wave, 'pseudo-tides,' and planetary wave characteristics, (2) mesopause dynamics and energetics at high geomagnetic latitude, (3) lower thermospheric dynamics and energetics at high geomagnetic latitude, (4) collaborative studies with other high-latitude instruments, (5) impact of high-latitude auroras on structure and dynamics, (6) plasma drifts, patches and blobs, (7) ionosphere-magnetosphere coupling processes, and (8) effects of geomagnetic perturbations.

这笔赠款将在极帽观测站连续三个季节维护和运行两台协调的“I类”光学仪器，并分析来自这些仪器的数据集，以系统地解决中间层和热层物理问题。该仪器已经到位，包括一个法布里-珀罗涉仪和一个全数字全天单色成像仪系统，该系统带有热电制冷的裸露CCD探测器和可编程的滤光轮。这两台仪器部署在“早期PCO”大楼中，于1996年5月完成了第一个完整的观测季节，并已公布了结果。法布里-珀罗涉仪的表现超出预期，结果将继续通过雪松和加拿大赞助的努力与航空学界分享。此外，这两台仪器将为研究生Genene Fisher提供培训，他将研究：(1)重力波、“伪潮汐”和行星波特征，(2)高地磁地区的中层顶动力学和能量学，(3)高地磁地区的低热大气动力学和能量学，(4)与其他高纬度仪器的合作研究，(5)高纬度极光对结构和动力学的影响，(6)等离子体漂移、斑块和斑点，(7)电离层-磁层耦合过程，以及(8)地磁扰动的影响。
